Oil prices extended the previous day's losses, fuelled by data indicating softer demand in the United States and fading fears of a regional war in the Middle East.

Investors looked past a sell-off on Wall Street Wednesday when worries hit tech firms that borrowing costs would be kept elevated longer than expected.

Comments from Fed officials reinforced the view that sticky inflation and a resilient US economy will keep the bank from easing monetary policy anytime soon.

A rally across global markets, which saw some hit record highs this month, has given way to concerns that valuations may be overdone, and analysts said the current earnings season is key to maintaining momentum.

Expectations for US rate cuts in 2024 have fallen from six predicted at the start of the year to just two, while some analysts have even warned of a possible hike.

"The US central bank remains on track to cut rates twice this year, most likely starting at its September meeting," said Solita Marcelli at UBS Group AG.

Oil dropped further after losing more than three per cent Wednesday on figures showing a forecast-busting build-up in US stockpiles that raised questions about demand in the world's top economy.

Relief that Israel had held off any retaliation for the weekend's missile attack by Iran -- soothing fears of a conflict between the Middle East foes -- also weighed on oil prices.

Foreign exchange markets are also being closely followed after the dollar pushed uncomfortably higher against its peers.

Particularly in focus are the yen and won after US Treasury Secretary Janet Yellen joined her Japanese and South Korean counterparts in saying they were keeping an eye on movements.

The statement came after South Korea's Choi Sang-mok and Japan's Shunichi Suzuki shared "serious concerns" about the recent weakness of their currencies and agreed to take "appropriate actions" to counter extreme volatility.

Analysts said the statement with Yellen suggested Washington would not push back against intervention by the countries.

The yen has lost almost nine per cent this year and won about seven per cent.
